Responses of Soil Macrofaunal Community and Diversity under Different Types of Vegetation on Soil Nutrient Pools in winter in Emei Mountain, China

To study its community characteristics under different types of vegetation in winter, soil macro fauna were collected and identified by hand picking in Emei Mountain in December, 2016. Soil nutrient pools and the amounts of microbial biomass were measured, and the diversity indices of soil macro fauna were calculated. We identified 667 soil macro fauna individuals belonging to 26 orders, 11 classes, and 4 phyla. The highest values of the Pielou (J) and Shannon-Wiener (H') diversity indices were established in the 0.5 cm soil layer of the evergreen broad-leaved forest (2.22 and 0.76, respectively). The lowest values these indices had in the 5–10 cm soil layer of the coniferous and broad-leaved mixed forest (0.51 and 0.17, respectively). The correlation analysis results showed that the numbers of soil macro fauna group were significantly correlated to soil temperature and MBC contents, and the number of soil macro fauna individuals was significantly correlated with soil water content. Therefore, vegetation type and soil microbial dynamics have a strong effect on the diversity of soil macro fauna communities, which further affect the soil nutrient cycle and ecological processes.
